. point or in the same station.

The object of this invention is to provide access to trains in any one of a number of underground, surface, or elevated railways, or railwayT tunnels or structures so closely arranged in respect to each other as to leave insufficient space for platforms or means of entrance and exit between them.

In the accompanying drawings, Figure l is a transverse section of a station of an underground-railway structure, showing my invention. Fig. 2 is a modification thereof.

Hitherto in` underground railways the several tracks have been arranged on approximate levels with landings or platforms atthe side of the walks, respectively, or between them, and stairways leading to these platforms from the street, either directlyr or through buildings. This varrangement of tracks and platforms between them on an approximate level requires lateral space for curves and turn-outs to admit the placing of said platforms. In some instances it may become desirable to 4confine the tunnels or tracks within a narrow space, so as to preclude locating the platforms between the tracks. Provision must then be made for access to more thanl one train at the same To this end the tracks at the station are arranged on different planes.

. Referring to the drawings, in Fig. l are shown four tracks, the inner ones A A being ona higher plane than the outer ones B B.

This location of t-he tracks may be brought about by a depression of the road-beds of the lside tracks at the station to such a depth as to bring the top of the trains on the side tracks slightly above the tracks of the inner roadway, as shown. A platform C is placed over cach of the side tracks adjacent to the streets and localities where sufficient room is lacking access can thus be had to express and way trains by a double deck or platform station and limited lateral space utilized for a number of tunnels or accessible tracks.

In Fig. 2 is shown a modification, Where the planes are reversed, the inner tracks A A vbeing below and the outer ones B B above. In this instance the road-bed ofthe inner tracks is in a depression at the 'station and the outer tracks are nearly on a level with the upper platform. The upper platform C is narrower than 'O and the lower platform E is as wide, extending beneath the side tracks and adjacent to the inner ones. The support of the side track may be a metallic structure with space beneath for access to the inner tracks; or it may be solid with a masonry or other arch formed therein, under which the lower platform extends. The double platform may be connected by a stairway I), as before, or directly with the surface or a building. The same principle is carried out here as in the arrangement in Fig. 1, the tracks being on different planes and accessible by means of a double platform.

That I claim is 1. In underground-railway stations, the combination of four adjacent tracks, of which the two-outer ones are arranged in different vertical and horizontal planes from the two inner ones, with platforms adjacent to each track, substantially as described.

2. An underground-railway station having tracks on different planes, the outer track being depressed below the inner, and a landing for the inner track extending over the which extends over the outer tracks, substanouter one, and a second landing adjacent to tially as described. y 1o the latter, substantially as shown and de- In testimony whereof I have hereunto subscribed. scribed my name.
